SPRNKLER.

Application led February 24, 1915.

Be it known that li, llaman H'. Drill-iii', a citizen of the lnited States. residing at New York cit, vfn, the county of New l'oi'lc and State o'l" New York.y have invented new and useful linl'n'ovenients in Sprinklers, oi which the following' is a specification.

This invention relates to automatic.sprinklers and it consists in the novel features hereinafter described and claimed.

An object ol the invention is to provide an automat-ic sprinkler ol simple and durable structure having a holding ineniber u sich is fusible at a coinpiu'atively low de- `free of temperature. and which when melted by excessive heat releases other members ot `the. structure whereby a vater pipe is opened and the water is permitted to ilow or sp1-inkle about the structure and extinguish tire which may be burning in the vicinity thereof.

'With the above object in view the sprinkler includes a nipple having a faine mounted thereon and a spreader mounted upon the-frame above the outlet opening of the nipple. A valve is arranged to seat upon the outlet opening of the nipple and a series of bars and legs are held in'norinal position with relation to each other by means of a suitable band or element. A block is adjust-ably mounted in the upper portion ot the i aine aud -ineans is provided lier Inoving the said block to engage the Vupper ends oitf the hars whereby the lower ends of the legs are held against thevalve which in turn is securely held in position upon the outlet opening; ot the. nipple. When the temperature ot the air in. the vicinity of the structure. raises, as 'tra' instance in the event of tire, the said Fusible band is melted and the. said bars and legis are permitted to fall by gravity away from each other whereby the valve is forced by the water pressure into the nipple away from its seat and the water inay strike the spreader and be deflected in all directions about the sprinkler.

ln the accompanying drawing:MFigiu-e 1 is a side elevation ofthe sprinkler with parts shown in section. Fig. 2 is a horizontal sectional view oi the saine eut on the line 2-Q oli Fig. 1. Fig. il is an under plan view it the spreader.

rlhe sprinkler includes a nipple 1 which is adapted to he screw-sorted in or otherwise secured to a water supply pipe not shown). An ovate frame 2 is provided upon the up- Specification of Letters Fatent.

per/ptntion oit" the nipple 1 and extends above the.. upper end thereof. The liranie 2 is provided at upperend with an upwardly disposed lug 25 upon which is seated a. spreader -la rl`he spreader #l is provided at its under side with a series of concentrically arranged corrugations and apertures (i pass transversely through the spreader l and are located in the valleys between the eorrugations A valve 7 is arranged to seat upon the upper or outlet end of the nipplev 1 and the said valve providedgat lits upper side with notches 8. Legs 9 rest at their lower ends in the notches S and the said legs are provided at their upper ends with outwardly disposed heads 10. The upper portions of thev legs l) diverge. from each other in a downward direction and the lower portions ot' the said legs 9 converge toward each other in .a downward direction best shown in Fig'. 1 of the drawing. The legs 9 are provided at the inner edges ot' their lower converging pois tion with inwardly ydisposed shoulders 11 and each of the. said legs are provided in the vicinity ot' their upper ends with pins 12 disposed at the sides of the said legs. A band 13 ot' fusible material, that is to say material which will melt at a ron'iparatively low degree ot' temperature surrounds the upper portions ot the legs 9 between the heads 1() thcreot and the pins 12 carried thereby.

The traine 2 is provided at its upper end and at its inner sideY with a socket 14 in which niovably mounted a. block 15. The block 15 is provided at its lower or under side with notches .lo which receive the upper ends ot bars 17. Said notches may en` tend all ot' the way across the block 15. The lower ends of thc bars 17 bear against the 'upper edges of the shoulders 1lv as best shown in Fig. 1 ot' the drawing. A screw 1S is threaded through the upper end of the traine z2 and the lug El thereot` and at its lower end engages the upper suriace of the block 15. The. said screw 1S also passes transversely through the center of the spreader l. After the screw 1S is inserted in proper position in the. upper end of the traine 2 its head may be flattened from the shape shown in dotted lines in Fig. l to the shape. shown in heavy lines in thc said iigure thereby formingl an overlapping head 19 the edge portions of which bear directly against, the upper surihiee of the spreader 4.. lWhen the screw 18 is in propel' position Patented Jan. 1S, 1916.

in the lug 3 the said screw maybe secured with relation to the, lug by means of a pin which is passed transversely through the lug and the said screw.

Assumingthat' the parts are in 'the positions as shown in Fig. l ot' the drawing and 4the band 13 is subjected to a comparatively high degree of heat the said band melts and hence the bars 17 and legs 9 are permitted to 'tall from between the valve 7 and the block l5. lnasniueh as the valve 7 bears against the upper end otl thev nipple 1 which is eonnected with the water suppl)v pipe (not shown) the pressure olI the water against the under side oli the valve 7 yforces the said valve awav from the nipple 1 and the water squirts up against the under side ot the spreader el and b v the said spreader is delleeted in all directions around the sprinkler. Sonie ot the'water :nav pass up through the apertures l through the spia-ader and danipen objet-ts which niav be located innnediatelv above' the said spreader. Thus it will lie seen that when the sprinkler is subjected to` unusual conditions, that .is to sav to an excessive temperature, it ,auton'iatieallvnoperates to release the valve thereby liberating a column ot water which is sprinkled about the structure in all directions.

To assemble thev pa rtg the valvel 7 is placed upon, the upper end of the nipple. 1 and the lower ends of the legs 9 are placed inthe notches S. The bands 13 is then placed in position around theI upper ends ol' the legs 9 and the bars 17 are extended down through the band 13 and engage with the shoulders 11. 'Vl`lie`upper e'nds ot the bars 17 are then seated iii notches 1li ol the block 15 and a screw 1S turned wherebyv the. said block is ioi'eedin a downward direction and the bars 17 liearii'ig against the. shoulders 11 hold the legs downsecurely against the valve 7 thereb)Y holding the said valve in position upon the upper end ot' the. nipple 1. 'llie li'ead 19 ot the screw 19 is then flattened as' shown in heavy lilies in Fig. 1 and consequently the parts cannot be loosened accidentlvy 0r by mischievous persons but the. band 13 must be broken or removed in order to release the valve, 7.

From the above vdescription taken in conjunction with the aceoinpaiivii'r drawing` it will be seen that' a sprinkler ot simple and durable*structure is provided and that the parts mutually cooperatel with each other in an automatic nianner to release and sprinkie av column of water about the structure when the. structure. is subjected to an excessive heat.
